CCFL lamp works
Cold cathode fluorescent lamp is sealed in a glass tube inert gas Ne + Ar gas mixture, which contains trace amounts of mercury vapor (several mg), and the phosphor coating on the glass wall, the second electrode with a high pressure between the high frequency electric field, the mercury vapor is excited in this electric field which produce energy release luminous effect and emit a wavelength of 253.7nm ultraviolet light, while the inner wall of the phosphor atoms due to UV excitation and enhance their energy levels, when the atom is anti-radiation back to the original low-energy bands visible light (wavelength of visible light by a phosphor This material characteristics of the decision).

Spin-coated glass
Mainly for the semiconductor manufacturing process locality planarization technology. SOG dielectric material is a liquid containing a solvent in a spin coating (spin Coating) mode, uniformly coated on the wafer surface, depositing a dielectric layer to fill the concave holes. After heat treatment and then, the solvent can be removed, leaving the wafer on watch curing (Curing) Approximate after silica (SiO2) a dielectric material.
RSDS (slight differential signal) and LVDS (Low Voltage Differential Signaling) preliminary knowledge
Low voltage differential (differential) signal (signal) and Reduced (reduced, reducing) Swing (swing, swing) differential signal, if there is no formal national title, tentatively I call low-voltage differential signal and a slight differential signal. Although the two solution (solution, answers, solutions) are different, but the substance is similar, the purpose is to reduce the EMI (electromagnetic interference), specifically for the video card and LVDS LCD driver board communication between T-con, RSDS for T-con and a source driver chip communications. The current T-con are integrated LVDS and RSDS the receiving end of the transmission side. With a laptop, for example, video signal is first fed into the LVDS transmitter chip, after treatment, the original 18-bit RGB signals, three control signals and a clock signal of 22 signal becomes eight signals, and This eight lines are divided into four pairs, each pair of intertwined and sent to T-con chip (Why entwined it? studied physics people should know that such a magnetic field generated by each line can cancel each other out, Note: Each pair of lines The current form a loop). While the voltage amplitude reduced to a few hundred milli-pay.
To know the lcd module and the volume of traffic between hosts is huge, very high frequency, if you do not use LVDS and RSDS, EMI generated enough so the TFT LCD Display is not normal, and if the laptop, but also interfere with other parts of the work.
After using Lvds and rsds, the benefits are: 1. Reduce EMI. 2. Reduce interface connections three lower voltage 4. Operating frequency can reach 455Mbps (XGA), 5 to reduce PCB space

Note: LVDS and RSDS is actually two IC, if the T-con is not integrated, they are used in pairs, if integrated, it is to find out the T-con model, then choose the appropriate LVDS and RSDS transmitter chip to accept chip.
T-con is the Timing (set time) Control (control, domination), LCD timing controller, LCD driver board is the most important component.
